Motion vector coding with selection of an optimal predictive motion vector
Jungyoup Yang · Optical Engineering · 2009
A new motion vector coding method with optimal predictive motion vector selection is proposed. To improve compression performance, the proposed encoder selects an optimal predictive motion vector that produces minimum bits for motion vector coding. The proposed decoder estimates the optimal predictive motion vector without additional information for indicating which predictor is to be used at the encoder side. Experimental results show that compared to the H.264/AVC standard, the proposed scheme improves coding efficiency for various video sequences.
